棉花野生种质资源的育种应用研究与前景
Breeding Applications and Prospects of Wild Cotton Germplasm Resources
摘要
Abstract
Domestication and long-term breeding have led to the genetic bottleneck effect that significantly reduces the genetic diversity of cultivated cotton,limiting its potential for the development of new varieties and its ability to adapt to future challenges.Wild germplasm resources,however,serving as an important gene pool,may provide abundant genetic diversity for cultivated cotton improvement.This review systematically summarizes the latest advances and challenges in the study of cotton wild germplasm resources,including genetic diversity research,the identification of superior stress-resistant resources,the exploration of homoeologous tetraploid repeat genes controlling complex agronomic traits,and the creation of hybrid breeding materials.It also identifies four critical scientific issues that need to be addressed to promote the efficient utilization and breeding innovation of wild cotton resources.Future research will further leverage the superior genes of wild germplasm,combining genomics,transcriptomics,epigenomics,and other multi-omics technologies to identify key functional genes and their regulatory mechanisms,decipher the mechanisms of photoperiod sensitivity,and,in conjunction with gene editing technologies,accelerate the transfer of superior genes into cultivated species,thereby driving innovation and development in cotton breeding.关键词
